28.7% of students here are eligible for free or reduced-price lunch. That describes the circumstances families arrive with, not how the schools perform, so it is shown and not scored.

Public schools only, from the NCES Common Core of Data, placed by ZIP code — which schools are in this place, not which one a particular address is zoned for. A dash in a proficiency column is a gap in the federal file, not a bad result. Proficiency is measured against Connecticut’s own standard, so it is ranked within state. How to read school figures.

People moving in and out

Based on the address on federal tax returns, compared with the same filers a year earlier. It counts people who file, and sees a move only when the address on a return changes. Domestic moves only: people arriving from abroad are left out. This is the figure for Western Connecticut Planning Region, CT. IRS Statistics of Income, filing years 2022–2023.

The Census Bureau's Building Permits Survey lists only jurisdictions that issue their own permits, and Greenwich, CT is not one. This is the figure for Western Connecticut Planning Region, CT, which contains this city.

The hazards accounting for most of this area's expected annual loss are inland flooding, hurricane and earthquake, with inland flooding alone responsible for 71% of it.

Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). FEMA publishes at county level. City values are the population-weighted mean of the counties the city overlaps, using AreaProfile place-to-county land-area weights. FEMA does not endorse this presentation. Higher physical resilience means lower exposure.

Below these are deaths rather than offenses, published for the county. The two measure different things and are not comparable with each other.

Greenwich's police department reported 17 violent offenses per 100,000 residents, lower than most places with a department reporting. Property crime runs at 716.

Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides, so the firearm figure and the homicide figure above it count some of the same deaths twice over. They overlap and should not be added together.

Reported by Greenwich Police Department for a population of 64,915, across all twelve months of 2025. That department covers a noticeably different population from the 14,792 in this place itself, so it polices an area wider or narrower than the boundary used elsewhere on this page. Offenses are published by police department rather than by town, so this department was matched to this city by name within the state. Reported crime counts what was reported to and recorded by police.

Offenses are reported to the FBI by Greenwich’s own police department and shown only where it reported every month of the year; a partial year is withheld rather than scaled up. Reported crime is what police recorded, which is not the same as what happened. Death rates are crude rates — deaths divided by population, not adjusted for age — except where a count was too small for the CDC to publish and it modeled the rate, which the card marks. They come from provisional death certificate records, published by the CDC by county and not below it. So they describe the county around Greenwich (Western Connecticut Planning Region) rather than Greenwich itself. Neither is part of the Area Score. How to read crime rates and death rates.

6 major airports lie within 100 miles, the nearest John F Kennedy Intl at 28 miles.

Airport identity, position and runway data come from the FAA. “Major airport” is an AreaProfile classification — a public-use civil airport with a paved runway of at least 8,000 feet — not an FAA hub designation. Distances are straight-line, not driving distance.
